RUBY TOLCI-IIN, OF ST. LOUIS, MISSOURI.

EAR-STUD FASTENER.

To all whom 25 may concern.'

Be it known that I, RUBY TOLCHIN, a subject of the Czar of Russia, andnow residing in the city of St. Louis and State of Missouri, haveinvented a new and useful Improvement in Ear-Stud Fasteners, of whichthe following is a specification.

This invention relates to jewelry and more particularly to ear studfasteners.

It has for its principal objects to produce a simple, compact andeflicient securing device which can be readily applied and detached andwill not accidentally work loose, and to obviate the disadvantages ofthe ordinary screw fasteners for ear-piercing studs.

The invention consists in the parts and in the arrangements andcombinations of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification andwherein like symbols refer to like parts wherever they occur,-Figure 1is a side View partly in section, on a considerably enlarged scale,illustrating an ear stud with a securing device applied embodying theinvention; Fig. 2 is a similar view, the securing device being detached;Fig. 3 is a section on the line 3 3 of Fig. 2; Fig. 4 is a section onthe line 4-4 of Fig. 2; and Figs. 5 and 6 are sections similar to Figs.3 and 4 illustrating a modilication of the invention.

The stud 1 may be provided with any ordinary or desirable mounting 2 forthe stone 3. The stud is adapted to receive a `'fastener comprising atubular portion 4 which extends diametrically through a circular handleportion 5. One half of this circular portion is tubular and has a curvedlatch pin 6 slidably fitted therein. Behind the latch pin is a spring 7,which yieldingly holds it in projected position, which position islimited by a stud S working in a slot 9 in said circular handle portionand serving as a catch for withdrawing the latch pin. The end of thelatch pin is beveled, as at 10, and the end of the ear stud 1 ispreferably beveled, as at 11, so as to engage said beveled portion ofthe latch pin and move the pin back against the spring when the fasteneris applied.

The stud may be provided with a recess 12 or perforated all the waythrough, as desired, so as to receive the end of the latch pin 6; and tofacilitate the proper positioning of the holder with respect to the studSpecification of Letters Patent.

Serial No. 752,919.

so that the beveled end portion 11 of the stud will coperate properlywith the beveled end portion 10 of the latch pin 6, the stud may begrooved longitudinally, as at 13, and the tube 4 provided with a rib 14which is a counterpart of the groove. In this way it is impossible toapply the fastener without first bringing the stud and fastener inproper position for the rib 14 to` enter the groove 13.

The fastener is preferably provided with an annular collar or plateportion 15 which is dished slightly, as at 16, so that the end of thestud 1 may be readily guided to the tube 4, and said collar 15 alsoaffords a comfortable bearing behind t-he ear. The circular portion 5affords a convenient grasping piece for manipulating the fastener; andby having a part of said circular portion formed tubular, so as to housethe latch pin 6, the device is obviously made compact and yetconsiderable length is allowed to the latch pin and the spring.

Instead of grec-ving the stud 1 and providing a rib in the tube 4, thestud may be flattened on one side, as at 17 and the tube correspondinglyflattened, as at 18, to insure the proper application of the fastener;and, obviously, the cross section of the stud and tube may be shapedotherwise to accomplish the same result. Therefore, I do not wish to belimited to the eXact construction and arrangement shown.

TWhat I claim is:

1. rIhe combination with an ear stud, of a detachable fastener therefor,said fastener comprising a tubular member sleeved on said stud, saidstud and tubular member having counterpart coperating` portions arrangedso that they fit only when placed endwise in one particular relation toeach other and whereby they are permitted relative longitudinal movementbut are prevented from turning independently of each other whenassembled, an arcuate tubular member secured at its opposite` ends tosaid first-mentioned tubular member and opening at one end into saidfirst-mentioned tubular member, and a correspondingly curvedspring-pressed latch pin working in said arcuate tubular member so as tonormally project transversely into said first-mentioned tubular member,said ear stud having a transverse opening adapted to receive the end ofsaid latch pin.

2. The combination with an ear stud, of

a detachable fastener therefor, said fastener comprising a tubularmember sleeved on said stud, said stud and tubular member beingrelatively grooved and ribbed longitudinally on one side so that theyfit only when placed endWise in one particular relation to each otherand whereby they are permitted relative longitudinal movement but areprevented from turning independently of eachv other When assembled, anarcuate tubular member secured at its opposite ends to saidiirst-mentioned tubular member and opening at one end into saidrst-mentioned tubular member, and a correspondingly curvedspring-pressed latch pin Working in said arcuate tubular member so as tonormally proj ect transversely into said first-mentioned tubular member,said ear stud having a transverse opening adapted to receive the end ofsaid latch pin.

3. The combination With an ear stud, of a detachable fastener therefor,said fastener comprising an integral structure including a tubularmember, two semi-circular members merging at their ends With saidtubular member on opposite sides thereof, a collar at the inner end ofsaid tubular member and Copies of this patent may be obtained formerging with the adjacent ends .'of'said semicircular members, saidtubular member bel Aand opening at one end into said first-mentionedtubular memberl near the outer end thereof, =and a spring-pressedarcuate latch pin Working in the tubular portion of said semi-circularmember so as to normally project transversely into said first-mentionedtubular member, said ear stud having a transverse opening A adapted toreceive the end of said latch pin.
